Can anybody explain if following two scenarios are valid and where:
1. UAC receives 407 for the request it sent out and again
it gets 401 for the request it sent out in response to previous
407
2. UAC receives 401 for the request it sent out and again
it gets 407 for the request it sent out in response to previous
401
Clearly, any series of responses can be generated if the
routing of the second request is not the same as the routing of the
first. (Which could be due to agents becoming available or
not-available, or time-dependent routing rules.) There are other
messy situations that can generate these scenarios, too.
If a request is challenged more than once, the UAC should add further
Authorization headers in response to each challenge. This process
ends when the UAC has no credentials for any of the challenges it has
not yet satisfied, or when some predefined limit is reached (to
prevent pathological behavior).
